The notion of sexual imprinting, or sexual preference based on 
				parental characteristics, has long been studied by evolutionary 
				psychologists, who research mental and psychological traits 
				relating to natural selection. Some experts suggest imprinting 
				has persisted because it increases genetic compatibility between 
				mates.
				
But this detailed mode of measurement is a new tool for 
				mapping how sexual imprinting works. 
				Forty-nine Polish women were asked to select the most 
				attractive face from a series of 15 photographs. Their choices' 
				facial measurements were then compared with those of their 
				fathers' faces. Ears, neck, shoulders and hair were excluded to 
				emphasize the eyes, mouth, chin and nose and to prevent results 
				from being influenced by style choices.
				Women who reported good relations with their fathers tended 
				to choose men with more facial similarities.
				Sexual imprinting is believed to be independent of genetics, 
				since previous studies have shown that women's positive 
				relationships with their adoptive fathers also led them to 
				choose mates who looked like dad, Dr. Boothroyd wrote in the 
				study.
				The research was released with celebrity examples such as 
				Nigella Lawson, the British food writer whose husband, 
				advertising executive Charles Saatchi, shares the elegant facial 
				proportions of her father, Nigel Lawson, a former chancellor of 
				the exchequer. 
				Here in Canada, a cursory scan of photographic evidence 
				suggests that Belinda Stronach's ex, Johann Olav Koss, resembles 
				her father, Frank, more than does her sometimes-escort Tie Domi. 
				And Caroline Mulroney's hubby, Andrew Lapham, has a certain 
				Brian Mulroney air about him.
				Toronto-based professional matchmaker Ruth Claramunt says the 
				research backs up her observations on the dating front line with 
				her company Hearts Introduction Service.
				“It's so true,” she says. “They could have just asked me!”
				
				Recently, Ms. Claramunt says she watched science in motion 
				when a female client chose a daddy doppelganger.
				“She was gorgeous and tall – she could have had a GQ type,” 
				the matchmaker says. “But she wanted a huge teddy bear like her 
				father. That's who she's with now.”
				Men, on the other hand, do not tend to choose women based on 
				their relationships with their mothers, she says.
